Fig. 2 is another embodiment electrical block diagram of start-stop control system of the present invention.
In figure, the Chinese implication of each English mark is:
EMS: driving engine lowpass system; SSC: on off controller; OBD: On-Board Diagnostics (OBD); IBS: can only battery sensor.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1-2, a kind of automatic gear car start-stop control system, comprise coiling accumulator, battery sensor, starter motor, on off controller, EMS wakes normally closed relay and starter motor relay up, described on off controller comprises acquisition module and ECU control processor, described acquisition module gathers automobile information and sends to ECU control processor analyzing and processing, described EMS wakes normally closed relay up and is connected with engine management system by EMS wake-up signal line, the switching that described on off controller drives by first via flash and the low limit of the first via drives control EMS to wake normally closed relay up, described on off controller drives by the second road flash and low limit, the second tunnel drives the switching of controlling starter motor relay, described starter motor relay output end is connected with starter motor.
Wherein coiling accumulator has following characteristic: minimum 15000 times of the number of starts is 3 times of conventional accumulators; Starting current is 3 times of conventional accumulators; Maximum current output in the time of subzero 18 ℃ is up to 600A.Wherein actuating motor has following characteristic: 220,000 warm startings, 3.5 ten thousand cold starts; Cranking noise is low; Starting speed is fast.
Described acquisition module can adopt OBD communication module, and this module is connected in automobile OBD diagnostics port by wire harness, communicates with automobile.OBD communications protocol comprises CAN, Kline etc., and the present embodiment be take CAN communication as example.According to ISO-15031, on off controller can obtain engine speed from diagnostics port by CAN-H and CAN-L, cooling water temperature, the information such as Throttle Position aperture; According to the self-defining agreement of producer, can obtain gear from diagnostics port, brake switch, door contact interrupter, bonnet switch, the letters such as air conditioning switch, ECU control processor is according to these information and in conjunction with control policy, the start and stop of control engine.And OBD diagnostics port can provide VDD-to-VSS on off controller.The advantage of the method is: can avoid brokenly line, wire harness is fewer, and safe and reliable, is easy to promote.ECU control processor is according to these information and in conjunction with control policy, the start and stop of control engine.
The another kind of embodiment scheme of the present invention is: ECU control processor obtains relevant information by sensor rigid line, as obtained engine rotational speed signal from crank-position sensor end, from engine water temperature sensor end or water temperature signal, from throttle valve switch sensor side, obtain acceleration/accel pedal position signal, from gear signal, obtain current gear, from air conditioning switch, obtain air conditioning switch signal, from brake switch, obtain brake switch signal, from door contact interrupter, obtain door contact interrupter signal, from bonnet switch, obtain bonnet on-off signal.And on off controller power input is connected with external power supply by connection lead, described on off controller earth terminal by connection lead be connected publicly.
The wake-up signal KL15 of on off controller of the present invention is connected on automobile key ON gear (ignition lock) signal wire (SW), once automobile key is got to ON shelves, on off controller is just activated.Intelligent battery installation of sensors, on the negative pole of storage battery, gathers battery temp, electric current, and the information such as voltage, accurately estimate the SOC of storage battery, by LIN communication, pass on off controller;
On off controller of the present invention installs start stop system relevant information display instrument additional; instrument receives the relevant information from off controller by RS-232; show the number of times that on off controller control engine starts; the number of times that on off controller control engine is shut down; the on off controller run duration engine running time; the oil mass that the time that on off controller control engine is shut down and start stop system are saved, battery SOC, the information such as engine cooling water temperature.
ECU control processor is accepted automobile relevant information, and when meeting engine shutdown condition, on off controller drives by 1 road flash and low limit, 1 tunnel drives to control this EMS and wakes normally closed relay up and disconnect, thereby realizes the function of engine idle shutdown.The advantage of the method is: by disconnecting EMS, wake normally closed relay up and control electricity under EMS and kill engine, simulated engine orderly closedown flow process, guarantees that stopping process is safe and reliable.Meanwhile, when EMS wakes normally closed relay up and can guarantee that start stop system is deactivated or broken down, do not affect engine work.
When meeting engine starting condition, on off controller, by drive a road flash to drive low limit, He Yi road to drive starter motor relay closes certain hour in control relay box to drive starter motor simultaneously, is being restarted driving engine by starter motor simultaneously.Long for fear of starter motor and driving engine binding time, when the starter motor relay closes time, surpass 0.8S, or engine speed is greater than 1000rpm, the disconnection of on off controller control starter motor relay.If there is no for the first time smooth start the engine, as long as meet entry condition, start stop system can be after 0.3S again closed starter motor relay restart driving engine.When the start and stop frequency of failure is greater than 4 times, start stop system can enter failure mode.
On on off controller, add start and stop enable switch, described start and stop enable switch is connected in series with the wake-up signal of on off controller by connection lead.The start and stop enable switch installing additional can allow the autonomous selection of chaufeur whether enable start and stop function, and when chaufeur is pressed start and stop enable switch, start stop system is started working, otherwise start and stop function is inoperative; When start stop system et out of order, the flicker of start and stop enable switch LED lamp.
When following condition all meets, on off controller is just understood control engine and is shut down:
A. safe driving condition: bonnet is closed, closing of the door, safety strap is fastened;
B. storage battery SOC is greater than 80% calibration value,
C. engine cooling water temperature is greater than 75 ℃,
D. start and stop enable switch is closed;
E. automobile completes cold start-up for the first time, and driving engine time of run surpasses 30S;
F. automobile is at upper once run duration, and the speed of a motor vehicle is greater than 10km/h, or maintains as you were always;
G. the speed of a motor vehicle is 0, and engine speed is lower than 850rpm;
H. chaufeur is being stepped on brake pedal always, and gear is allocated to N shelves; Or stepping on brake pedal and maintaining 0.8S, and gear is being allocated to P shelves;
When following condition meets, start stop system control engine starts:
A. safe driving condition: bonnet is closed, closing of the door, safety strap is fastened, meanwhile,
B. when gear is during at N shelves, loosen the brake; When gear is during at P shelves, again step on brake pedal, or light step on the accelerator,
C.SOC is lower than 60% calibration value, and for example 60%, or
D. water temperature is lower than 65 ℃;
Wherein a condition must meet, and any one meets b, c and d and can start by control engine.
More than show and described groundwork of the present invention, principal character and advantage.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is by appending claims and equivalent circle thereof.
